Nucleotide Groups for DNA & RNA
|
DNA |
RNA |
|
Adenine |
Adenine |
|
Guanine |
Guanine |
|
Cytosine |
Cytosine |
|
Thymine |
Uracil |
|
DNA complimentary nucleotide pairing thus: CYTOSINE-GUANINE GUANINE-CYTOSINE ADENINE-THYMINE THYMINE-ADENINE ALWAYS
|
RNA complementary nucleotide pairing: Thymine has been replaced with URACIL ADENINE : URACIL URACIL : ADENINE CYTOSINE : GUANINE GUANINE : CYTOSINE ALWAYS

Types of RNA |
|
| Ribosomal RNA (rRNA) | Forms ribosomes |
| essenger RNA (mRNA) | Long chain that carries code from the DNA to the cytoplasm |
| Transfer RNA (tRNA) | Long chain that carries code from the DNA to the cytoplasm |
|
Nucleotide sequences |
|
| triplet: | DNA 3 base codes that translate into one amino acid |
| codon: | mRNA: 3 bases complimentary to triple |
| anticodon: | tRNA: 3 base codes complimentary to codon |
